g In this next question electrons of a given kinetic energy - instead of photons - are incident to an atom. While photon absorption is an all or nothing process, electrons can loose also just some kinetic energy. Interaction of these electrons with the atoms in the target may result in emission of photons. Which of the following statements are true? Select all answers that apply. The kinetic energy of the "beam" electrons exceeds the binding energy of an electron in the target atom. The atom becomes ionized; left behind is a vacancy in a lower energy bound state. The kinetic energy of a "beam" electron exceeds the energy necessary to excite an electron (in the target atom) into an unoccupied higher energy level of another bound state. Electrons (from the beam) can only give off all their kinetic energy in one interaction. Electrons (from the beam) can interact several times with the target atom and lose some of their kinetic energy in each such interaction process.
